' Lon'gIsland, and State of New Yorlghave in vented' certain new'anduseful Improve;- ments in DiffusionfOutlets for Conduits,- of whichthe followingis av specification.

My invention relates to diitfusion outlets forco11(:luits, andparticularly to'an outlet cover or guard, which not only lessens jdangerof stoppage, but also aids; 1n effecting discharge from the conduit.The invention is particularly applicable" to submerged sewer pipeoutlets.

It is a. frequent practice for municipalities to pipe theirv sewage ofwater, such as av river, ti'dal basin, etc.,

and to discharge the sewage into the latter through ports formed atintervals in the length of the sewer pipe. Often object's sus pended inthe water of submergence' become lodged in the outlet openings of theconduit and block discharge therefrom. It requires constant inspectionof the line to keep the openings free from this trouble; The object ofthe present invention is to provide a diffusion block adapt-ed to'bearranged at such 7 ports and serving not only to prevent stop pagethereof, but also to deflect the flow of the water of submergence pastthe opening so as to assist in the discharge of the sewage from thepipe. While I have referred to submerged sewers as the type ofconstruction to which the invention is particularly applisection on theline 14- 14,

to a neighboring body cable, it will be understood of coursethat' theconstruction may 'be used inrnany other in stallations to advantage-,and1010 not liinit its application, therefore, to sewer pipe. 4

V Referring to the" constructions shown in Figs; 1 to 3,1the conduitQO,through: which the liquid to" be discharged flo wsp is indi cated asniadelrom concrete,'and has a pe ripheral port 21 formed thereinthrough: which the liquid escapes In order' to prevent,-' as 'far aspossible, the retention of any" solids at the mouth of the port, itsmazrgin isround'ed, a's at' 22', to affordasmooth pas sageway. As" willbe noted troni F-igl2ythe" port is here shownaslsubstantially rectangular in plan. Covering this opening' is a diiiiusion bloclz 23 which,wherefithe conduit is of concrete, may similarly bemolded fromconcreteaand its 'concavv'e seatfi may beset in grout on the pipe 20,to* assist in holding iti-n position. I have provided also a pair" ofsteelbands-25, which pa'ss beneath the conduit and over thebloclnwlierethey-are drawn tightby bolts QG'en'ga-ging the angle iron ends 527. Theblock thus forms an arch, which overlies the port 21 and affords lateraldischarge openings" 28' at right angles to the axis oi" the pipe." Castintegral with the block at its opposite ends, in'the direc tionof thelength'of the pipe; are deflecting plows or vanes 29 and 30. Wherethepipe is submerged in water wh-i'ch'flows in oppo"- site directions,as in a tidal basin, the vanes 29* and 30 deflect the current and divertit outward so thatat' the discharge ports the fiow'past the outlet is atan angle to the axis of the pipe". This not only tends to keep anysuspended matter in the water of submergence awayfrorn the aperture, butalso exerts a certainsuction effort which aids in'discharging. thecontents of the conduit.

WVhere the conduit is located in a stream, where the direction of flowisalways in-one direction, the diffusion block may have but a singledeflecting vane, pointed" rip-stream, as illustrated in- Figs. 4, 5'and6: Inthis case I have shown the'discharg'e 'portin'the pipe as:circular, and the diiiusion block is preferably located with itsupstream end wall adjacent the up-stream side of the discharge port. Themargins of discharge port '31 are outwardly flared to prevent clogging.

diffusion block has its discharge opening arranged at the down streamend of the block in the direction of the flow of the current. Thedischarge port 33 in the conduit is flared at its outer margin only, toassist in maintaining the aperture clear.

In Figs. 10, 11 and 12 the conduit is provided with a pair of dischargeopenings 34: and 35, which open to a corresponding pair of channels 36and 37 diverging from the axial line of the pipe and opening to thesides of the diffusion block. Obviously, the same effect is obtained inthis construction as in that first described by reason of thecurrent-deflecting vane 29 at the up-stream end of the diffusion block.

In all of the constructions, I have indicated small holes 38 in theblocks to facilitate their manipulation during manufacture andadjustment in position on the conduit.

Various other modifications in construction and arrangement of aperturesand discharge channels will readily occur to those skilled in the artwhich obtain substantially similar results, without departing from whatI claim as my invention.

I claim- 1. For use with a submerged conduit having a discharge port inits crown, a diffusion block adapted to be arranged over the port andshaped to deflect the water of submergence into an outwardly directedcurrent, and having a lateral discharge aperture communicating with theconduit port and leading thedischarge therefrom toward said outwardlydirected current in I the water of submergence.

2. For use with a submerged conduit having a discharge port, a diffusionblock adapted to be arranged over the port and having a lateraldischarge aperture coinmunicating with said port, said diffusion blockbeing independent of the conduit and having associated means embracingthe conduit for securing the same in position over the discharge port inthe conduit.

'3. For use with a submerged conduit having a discharge port, adiffusion block adapted to be arranged over the port and having alateral discharge aperture communicating with said port, together withprojecting end vane means for deflecting the liquid of submergence awayfrom the outlet of the diffusion block.

'41; For use with a submerged conduit having a peripheral port, adiffusion block having an arcuate seat adapted to rest on the conduit,an outwardly flared lateral dis-.

charge outlet from the diffusion block, and

a passage establishing communication between said outlet port in theconduit.

5. A difl'usion block of the type described having a passage adapted tobe placed in register with a peripheral port in a conduit 011 which theblock is adapted to be seated, a lateral discharge outlet to which saidpassage opens, and a deflecting nose at an end of the block andextending in the direction of the pipe length.

6. The combination with a conduit submerged in a flowing body of water,and having a peripheral port, of a diflusion block seated on saidconduit at said port and having a lateral outlet, together with adeflecting nose for said diffusion block, said nose being pointedup-stream, and serving to cause the water of submergence to be laterallydeflected at the block for the purpose specified.

7. For use with a submerged conduit having' a discharge port, adiffusion block adapted to be arranged over the port and having alateral discharge aperture communicating with said port and opening tothe water of submergence at a point above the crown of the pipe.

8. For use with a submerged conduit having a discharge port, a diffusionblock adapted to be arranged over the port and having a lateraldischarge aperture communicating with said port and extending in adirection substantially parallel to the transverse horizontal axis ofthe pipe.

9. For use with a submerged conduit having a discharge port, a diffusionblock adapted to be arranged over the port and having a lateraldischarge aperture communicating with said port, said block being shapedto deflect the flow of the water of submergence past the port away fromsaid aperture but in the general direction of the flow of said water ofsubmergence to pro duce a suction effort aiding the discharge from saidaperture.

10. For use with a submerged conduit having a discharge port, adiffusion block adapted to be arranged over the port and having anoutwardly flared lateral discharge aperture communicating with saidport, said diffusion block having a V-shaped plow end serving to deflectthe flow of the water, of submergence past said aperture in a directionto exert a suction effort at the aperture for the purpose specificed.

In testimony whereof I have signed my name to this specification.

EARL L. PETERSON.
